Precomputed Culling

Pixel perfect occlusion system that will significantly improve the performance of your scenes, without almost any overhead.

Using time of your computer, precompute/bake your scenes to gain a significant performance boost. The occlusion culling algorithm will find all visible meshes from each point on your scene, using the color-coding algorithm. Then it will save them efficiently and load only when needed.

Heavily occluded scenes like a two-story house with the interior on all floors gained us up to 240% in frame rate!. From 30fps to 72fps on Quest 2.

Open world scenes with flat chunked terrain, gained us 10-25%. From 47fps to 60fps on low-end mobile.
